That's right - one has Eileen Brady leading and Charlie Hales losing a statistical three-way tie, and the other has Hales winning a statistical two-way tie and Brady way behind. Go figure. I'm guessing that the Jefferson Smith camp is thrilled - since they're in second place in both.

A few additional data points for you to mull over:

SurveyUSA notes that "Among the 22% of voters who tell SurveyUSA they have already returned their ballot, Brady leads, with 36% to Smith's 29% and Hales' 26%." So, is she at 36% or 16%? They can't both be true.

Last cycle, polling impresario Nate Silver ranked SurveyUSA as the third-most accurate pollster in the country. Elway Research ranked #31.

In October 2010, SurveyUSA had Scott Bruun leading Kurt Schrader 51 to 41. Elway Research had it Schrader 50, Bruun 38. The actual outcome was Schrader 51, Bruun 46.

The SurveyUSA poll had a sample size of 563 likely voters, and a margin of 4.2%. The Elway poll had a sample of 400 voters, and margin of 5%. Bigger samples make for lower margins-of-error, though the Brady 16% can't be explained by margin-of-error.

My take? I think it's pretty hard to look at that 16% for Brady in the Elway poll and consider it anything but an extreme outlier. Six consecutive three-candidate polls over six months have had her between 21 and 26%. And with SurveyUSA pegging the already-voted group as being at 36% for Brady, the Elway number just doesn't make any sense. (And one more thing - I've heard a number of reports of some polling firm employing live callers who ask about an "Ee-leen Brady". No idea who it is, but a consistent mispronunciation would tend to skew the numbers in that poll.)

Here's one final data point for you: Today, Multnomah County elections reports that voter turnout is at just 8.77%, relatively low for this point of the election.

So, regardless of what you think of the polls, this much is true: The winning campaign is going to be the one that gets the most communication out to voters in the closing weekend - over the air, in the mailboxes, on the phone, and on the doorstep. If you've got a rooting interest, get to work and make a big donation. It'll all come down to the wire.

Wow! What a difference. I'm inclined to go with Survey this time. Larger sample and in the current election season they've been fairly close. Their count on returned ballots bodes well for Brady. Looks to me like a Brady-Smith runoff for the fall.

The discrepancies in Brady's numbers are unsettling, but the story all three of the recent polls tell consistently is that as more and more voters begin to pay attention to the candidates, undecided voters are moving to Jefferson Smith.

I'm proud of Jefferson for running such an honest, substantive campaign, and for refusing to pander to the powers-that-be for endorsements and contributions. As the voters discover him, they are rewarding him with their support.

We've got another 8 days of hard work to do, all of us, but I'm pleased with the direction the campaign seems to be turning in, and I'm hopeful that as more undecided voters make up their minds Jefferson will win his rightful share of their votes.

Stephanie,
I'm still waiting for any substance to come from Jefferson.
Please let me know what his plans are.
So far I've heard opposing the CRC, vaguely talking about growing small businesses, and including East Portland.
Sounds great, but that wouldn't qualify as substance.

Let's face it. While I do not believe the Elway number for Brady, she has clearly stumbled and flat-lined. Throw out the Elway poll and she has hit a wall, while the other two have gained. If voters are still making up their minds then the edge has to go to Charlie and Jefferson.

My personal belief is that Eileen did poorly in the debates and the newspaper interviews. People had higher expectations for her and expected her to do better, but she didn't come through when it counted.

you can't really compare the 36% from one survey with the 16% from another survey. It's 36%/28% in one. That's sort of interesting. If 22% have voted and Brady has gotten 36% of those it means, according to the SUSA poll, that she's favored by about 26% of those who haven't voted yet. That's quite a bit higher than 16% but just as much lower than 36%. In other words, it seems she's gotten her most enthusiastic voters to send in ballots early and that her support isn't quite as strong from here on in.

Still, having votes in is a very good thing. If Smith and Hales have more support among those who haven't voted, and if for some reason those ballots don't get in, that doesn't help either much.

One thing that clearly doesn't seem to depend on which poll you use: Smith is the large gainer of undecideds in the last month or so, and has wedged himself into a position of direct competitiveness with either candidate in any model. That's a pretty enviable position, and obviously the trend is a big opening to whoever can GOTV. Based on the way he's built the campaign, that would seem to be an advantage for Smith as well, if they can get that push.

So the message is sticking, folks seem receptive. Voter contact is paying off. All good news. The horse race isn't the point though, and it almost certainly won't settle anything permanent next week. But voters are responding well to Jefferson's "protect the general fund, bring the two Portlands together" message. Right on.

Very similar to what I've observed. For myself personally and a lot of my friends the more they've heard from Brady the more they tend to turn to Hales or Smith. My friends that really like experience turn to Hales but the people that like vision and forward thinking seem to turn to Smith, but both groups seems to really like Smith's message regardless of how they're voting. Brady has just seemed milquetoast to most people I've talked to about the race.

The Survey USA poll results from its 4/13 poll ought to be included in your compilation of poll results: It shows Brady - Hales - Smith at 34 - 22 - 15% respectively; now (5/7) the Survey USA poll has them at 28 - 25 - 27%. So the fall by Brady and "surge" by Smith which appears also in the Oregonian data is quite real. And it indeed does "make sense" for the 8.77% (already voted) sample voting for Brady to be at 36% at the same time the Elway poll says her support (including the 91% not voted yet) to be at 16% (May 6th), so you obviously put an editorial "spin" on that comment. Sure, polls are polls; but spin is spin, ok? Here's the missing link to the 4/13 Survey USA poll you omitted: http://www.surveyusa.com/client/PollReport.aspx?g=9460b098-a757-4fb3-8d78-e5ca885338ab

Oh, and as for your math. The 36% "already voted" group for Brady comes from the 22% of respondents that told SurveyUSA that they had already voted.

"Already voted" is a far different thing than "the ballot is at Multnomah County elections." Typically, after someone votes, the ballot sits on the dining room table for a while, then it goes in the mailbox for a while, then it's in transit, then it arrives and sits in a box at elections before getting barcoded.

Perfectly reasonable that Multnomah County has 8.77% of the ballots while 22% of voters say they've voted.

I think there's a big piece of the story omitted from this post, though. Given that we're all supposed to believe in the reliability of SurveyUSA, we should remark on the fact that by their reckoning Brady has lost 6 points overall while her lead among women has dropped from 28 points to 8 points, just in the last three weeks. This while Hales is stalled and Smith is surging.

The money quote from Survey USA goes like this:

Among women, Brady leads by 8 points, down from a 28-points lead 3 weeks ago. Among voters under age 50, Smith leads Brady by 9 points, a 25-point flip from 3 weeks ago, when Brady had led by 16. Among voters age 50+, Hales edges Brady by 4 points, and Smith, despite seeing his support nearly double, trails both. Among Republicans and Democrats, the non-partisan mayoral primary is tied. Among independents, Smith now leads by 8.

My takeaway is that Jefferson Smith is in a statistical tie for FIRST place and clearly has THE momentum in both surveys. Message to Jefferson supporters: Our efforts are paying off big time. Let's double down and shoot for the moon: 51%+, Mayor-elect Jefferson Smith! Yes we can!

I can't claim knowledge what "already voted" means, Kari, but your theory seems a bit stretched, no worries, just another observation on the "spin" of your math. My ballot is sitting on my side table, mayor's race is marked and ballot is signed; some races aren't marked. If I were polled I wouldn't claim I have voted, and I think people understand the act of voting in Oregon is more than "I marked my ballot." Voting, to me, is the moment I commit the ballot to the mailbox or drop it off at Elections!

I think people understand the act of voting in Oregon is more than "I marked my ballot."

Well, clearly not. If 22% say they've vote, but only 9% of ballots are in and coded by the county, there's clearly a 13% gap there.

And even if you're not counting the ballot sitting on the table, you're probably counting the ballot you've put in the mailbox. But that's still a 2-3 day gap before it gets delivered, coded and released in the daily count.

There's not really a gap though because those are two different measurements. I presume the 9% returned ballot rate is out of all the ballots that were mailed. The SurveyUSA poll is surveying likely voters; a subset of the general population whom presumably are more likely to turn their ballots in early.

unnoted throughout this discussion: the Survey USA poll started & completed AFTER the Elway poll. in other words, whatever Elway might have been measuring was already in the process of changing - which Survey USA showed.

this is like the Tour de France: Smith made a breakaway but didn't have the power to sustain. Brady has reeled him back in. once again, it comes back to which team can pull their lead rider to the end.

Sure there is. If the random sampling was done correctly, then the group of 500 should have returned their ballots at roughly (nothing is exact, this is all statistics) the same rate as the general population. If the random sampling wasn't done correctly, then the poll results are worthless.

I already commented on the Survey USA poll for KATU and may give comments in a while on the dueling polls for KGW.

I have a few comments from the analyst's perch. I would not disagree with the general sentiments expressed here:

(1) Smith is clearly surging but is going to have to rely on a big GOTV effort for a tough portion of the electorate
(2) Brady's support seems to be stalling or eroding but she could hold on
(3) There remains a great deal of uncertainty, both in the poll estimates and I believe in the electorate.

Some other disorganized thoughts:

I am generally a skeptic of robo-polls like Survey USA but they have the advantage of lots of repeated measurements, so while I may not bet on the specific numbers, comparisons between the two Survey USA polls can be made ASSUMING similar response / refusal rates. It's very difficult to compare Elway with Survey USA without knowing a LOT more about their methodology. Personally, I'd go with the local experts--DHM--because they have an investment in this state and in getting it right. It's encouraging that their numbers and Survey USA numbers are similar.

I am not sure how relevant Silver's comments regarding presidential primaries are to these results. The level of interest and coverage are simply light years apart. The one similarity is that these three candidates are not that different in my mind, and I suspect in many voters' minds, and that can lead to volatility. If you disagree with that statement, then the Silver commentary becomes less applicable.

Many have claimed that the undecideds are breaking for Smith. That is possible, but it is also possible that there is candidate switching going on--that's almost certain given Brady's early numbers.

Hopes for Brady: her supporters identify the "economy" and "schools" as important issues. These issues are strong motivators. She has the most "banked" votes (if you believe Survey USA).
Worries for Brady: apparent erosion in support, particularly among women.

Hopes for Hales: strongest support among > 50 who turnout at high rates, similar issues to Brady.
Worries for Hales: he's holding steady but doesn't seem to be picking up support. not sure what to make of the cell phone / landline number.

Hope for Smith: the trend line is very impressive.
Worries for Smith: his core support is young people who tend not to vote, particularly in primaries. The core issue for his supporters is "transportation" but only 5% of the respondents identify that as the top issue. Has he taken too longto break for the front?

Only thing I'd note is that the only comment on this thread from Nate Silver about presidential primaries is the random aside I posted in a comment.

Per Silver, his pollster accuracy ratings are a broad sample of a very narrow sort of poll:

These ratings pertain to just one particular type of poll: those for which the field work was conducted within the 21 days preceding a public election, which surveyed people about their voting intention in that election, and which was released into the public domain in advance of the election.

These ratings reflect polling for President (general and primary elections), U.S. Senate, U.S. House, and gubernatorial races since 1998. More recent cycles are weighted more heavily. This is a truly massive amount of data: roughly 4,700 polls.

To be sure, a mayoral race isn't a presidential, Senate, House, or gubernatorial race.

But it's also interesting to note that in the twelve years from 1998 to June 2010, Elway Research had released exactly ten polls in any of those kinds of races in the final three weeks of an election.

Actually, Paul, the analogy does hold! Favorite Bodemeister led this year's Derby almost the entire race, with I'll Have Another hanging back in the pack until very late, coming on to win only in the final furlong.

Even better, commentators noted that this was the first time in 138 runnings of the Derby that a horse coming out of the post from the 19th position won the race. Watch it here.
